Evidence? OF COURSE!
Have you even tried searching for it?
Google even says so for Chromium on its own official page!

You don't need to trust us. Trust Google, they are telling you legally if you want to listen.
Also, look up the handful of open bugs on the Debian but tracker, where known people, with name and faces (I've met some on conferences), showcase and share how Chromium calls home and sends encrypted data. They share their Wireshark logs.

Look up how Debian removed Chromium for a time, until some of it got removed upstream.
And all of this doesn't mean that Google cannot re-introduce it or add different approaches in new updates.
Plus, Google actively creates and pushes for their "standards" via Chrome(ium), which allows them to push for even more surveillance.
In addition, Chromium is not a community project. It's developed behind closed doors, with a secret roadmap, and a code dump happens on release. That's no way to develop the 90% of web browser market that society needs in this day and age. But, don't think you will care about that, do you? you are happy with papa Google for the foreseeable.
Tax the income of corporations not the profit. The same way you get taxed your VAT. That means that corporations can't tax evade: if they make income in a country, they get taxed. They can't go an declare the profit in the Netherlands or Ireland and skip paying taxes.
Create and use parallel institutions to allow society to thrive without needing to play the billionares economy game. Example: communication tools outside of a market involvement such as Lemmy, Element (matrix). Economy tools. Association tools. See the application of Dual Power by socialists, which is what you are proposing here, a redistribution of power and wealth.
