Google isn’t the company that we should have handed the Web over to Analysis: Microsoft adopting Chromium puts the Web in a perilous place. https://arstechnica.com/gadgets/2018/12/the-web-now-belongs-to-google-and-that-should-worry-us-all/
There is no good public company that we should trust.
On the plus side, Chromium != Chrome. It's open source, and companies can prevent data collection to some extent - maybe not as much as Firefox. I understand the need for multiple browser engines to show that standards are actually interoperable, of course.
Back in the day, we were just happy to have a fast search engine and we believed their "do no evil" BS. Facebook's shenanigans hadn't yet come to light and it hadn't dawned on us yet - if we don't pay for a product; we are the product! How stupid were we.
My favorite detail, currently not very visible outside the GCP universe, is their Network Service Tiers concept: https://cloud.google.com/network-tiers/
While the numbers aren't disclosed publicly, Google's been quietly building a backbone network between their datacenters that (I'm fairly convinced) could rival the public internet. It would be a relatively simple software update to nudge Chrome browsers on to this "premium network" via VPN, and suddenly we're no longer on an open internet.
Every time I see a bit of coverage that indicates Chrome's dominance is growing, I always wonder how long it'll be before a very helpful, very innocently-marketed "security update!" pops up, promising to solve spam and harassment forever.
