I am not personally endorsing any of these specific articles, so if you have an issue with what they say, I suggest contacting them through the link to the article.
I do think that they all point to the same thing, though. Apple doesn't use your data as a separate revenue source and their competition does:

Google, by contrast, not only sells phones and other devices, but also makes money off the ads (and the user data) that appear on those handsets, laptops and tablets. Amazon’s gadget-oriented business model wants to sell you things (like Amazon Echos) that will help sell you more things (through voice ordering) — a dizzying value proposition. And then there’s Facebook, which doesn’t appear to be selling its users much of anything at this point. But look more closely and you discover Facebook’s users (and their kids’ bath time photos) are themselves the products unwittingly feeding the social network’s revenue model."

Apple says: “With HomePod, only after ‘Hey Siri’ is recognized locally on the device will any information be sent to Apple servers, encrypted and sent using an anonymous Siri identifier.”
This means that not only will Apple only record people after they have requested the virtual assistant, unlike Google and Amazon, it will also not gather information on users for the purpose of advertising and marketing."

Apple, by virtue of its business model, has no interest in storing my personal data any longer than it absolutely has to, and no interest in monetizing my behavior.So not only does it keep Siri offline until it hits the trigger phrase, once it goes online it generates an anonymous token ID and transmits all data with end-to-end encryption. That way, never have to worry about entire meeting transcripts being stored in logs, employees violating my privacy and snooping on me, or my past data being exposed over due to some future bug, partnership, or request.
That's not to say I don't want Apple using my data to provide me with better direct services. I just want my data to be used for my benefit, not for the company's bottom line. Not unless I start getting a share of the money they make off of it. (Which is way more valuable than any 'free" app or service offered as compensation to date.)"

Apple introduced the Siri-powered device Monday at the Worldwide Developers Conference, making it clear from the get-go that voice commands will be anonymized and encrypted.
Voice assistants have already taken over homes with the Amazon Echo, Google Home and Microsoft's Cortana speakers. They've all raised privacy issues of their own, but Apple adds some scale to the concerns.
As the largest tech company in the world, Apple is often in the crosshairs of hackers and governments. For example, the number of security orders from US law enforcement to Apple doubled to about 6,000 during the second half of 2016, compared with the first six months of the year, the company disclosed in late May.
The HomePod won't always be listening to its users. Like Amazon and Google's voice assistant, a person activates it with a wake word or phrase. With the HomePod, it'll be "Hey Siri."
"Our team cares deeply about your privacy," Apple Senior Vice President of Marketing Phil Schiller said at Monday's keynote. "It has that magic phrase, 'Hey Siri.' Until you say it, nothing's being sent to Apple."
When the data does get sent, anonymization and encryption means your voice commands aren't tied to your Apple ID, and even the company isn't able to clearly view it.
So far, data stored on Amazon's servers is not anonymized. Google Home's assistant is able to access a user's search and location history and stores data on voice commands until it's been deleted.
The FBI declined to disclose how often it requests voice data from Amazon's Echo, but the retail giant has shown that it can retrieve Alexa recordings from specific users in a criminal investigation.
The encryption for HomePod conversations sticks with Apple's push for user privacy from the government, a mindset that also helped the company fight off the FBI's demands to unlock the San Bernardino terrorist's iPhone in 2016."

Not so Apple, which pitches itself as the lone defender of user privacy in a sea of data-hungry companies. While other data vampires slurp up location information, keyboard behavior and search queries, Apple has turned up its nose at users’ information. The company consistently rolls out hardware solutions that make it more difficult for Apple (and hackers, governments and identity thieves) to access your data and has traditionally limited data analysis so it all occurs on the device instead of on Apple’s servers."
