That is, if vendor lock in will even allow you to get some other product without having to replace every device in your home (and hope this new vendor doesn't do the exact same within a few years).
Fair consumer protection regulations are necessary in modern society, the "vote with your wallet" strategy doesn't scale.
It would require a massive amount of pissed off consumers, and a huge team to even drag them to court.
End result would be google paying a pittance and no one getting anything.
End of the day, a lot of lawyers would be paid well and google would shrug it off as a cost of business.
I think it would be best if wrongdoers had to make consumers whole and also pay the costs of holding them accountable. But our system currently doesn't work that way, and in that context, it's still worthwhile to have lawyers motivated to raising the cost of wrongdoing.
For everyone else in tech, I suppose we can all vow to never purchase Google products as gifts for family.
