Who are you gonna buy from instead?

Your point, I suspect, is well-taken: choices are limited. Preference would be... any business which doesn't have the information to leak it in the first place. Retail, cash? Does that still exist? Anyway, this "we'll share excessive information with too many partners" pattern is far too normalized. Eventually I may be forced to choose the forest over buying [or building] another computer.

Realistically, if I had to buy: my employer, probably, given a reasonable discount. Unless you know a business that doesn't eagerly share personally identifiable information [which ends up leaked]... I'll aim for reduction, not resolution. I'm sure you've heard the quip about making Perfect the enemy of Better.

Regardless, and more fairly: with prices squeezed, and the pile of hardware I already own and ignore [including several old-school towers, both Framework desktop/laptop, and Steam Deck/Machine], I'm not foreseeing much shopping. Big loss on their part, I know; wish that was the intention.
