Capitalism. Specifically, the stock market. IPOs make good companies into bad companies.
Being owned by stockholders effectively removes any amount of "human" in the company's choices and direction. There becomes a single goal, to which everything else is sacrificed: make stock prices go up in the short term. The C-suite execs will say all sorts of other shit, but any appearance of accountability or altruism is solely geared to making more money at any cost. Any leadership with a soul will be forced to either give up trying to be "good", or they leave.
Google--not really a fan of the company, but the Pixels have been solid for me. The cameras have always been great, and weirdly, the bootloader has always been easy to unlock (I'm running LineageOS on my Pixel 7), so you can still get some modicum of privacy if you like.
