This is so wrong. What's the solution? Google class action lawsuit?

Start actively divesting of Google where possible. There are a lot of 'Switching to 100% European cloud' stories hitting HN lately. The more things like this happen the more stories like that will be there. Google and US tech are becoming toxic at many levels and an appropriate response is to mitigate risk by going to other providers.

You're going to sue Google for following the law of the land they're incorporated in? And demand that they - as a mega corporation - just ignore laws?

How about making sure that your laws don't authorize ICE data requests? How about that?

Realistically? Treating visiting or studying the USA as visiting or studying in North Korea. Would you stand in Kim Jong square and protest their foreign policy? If you would I salute you. If something terrible happens, I will not blame you, the victim. But if you surprise pikachu at the results, you are a moron. Foreigners will end up making a choice -- study or protest -- but don't expect they'll be able to manage both.

The powers that be in the USA have signalled they won't tolerate foreigners protesting state department policy on their soil. This is obviously unconstitutional. But it won't be changed through lawfare.
