I love it, but it was pretty messy a lot of the time in various different ways. My impressions were:
Season 1: Brilliant, really good science fiction
Season 2: Fun episodic comedy sci fi
Season 3: Sometimes weird, sometimes gruesomely tedious
Season 4: Trying to be more like a normal comedy TV show, results mixed
Nobody will be able to give you a definitive answer. Google's ways are unknowable. You are running the risk of losing your Google account by having a Google account.
The sight of so many people around the world who had always been unequivocal supporters of anything and everything Israel did slowly changing their minds as the horrific scope of the violence inflicted on Gaza continues to escalate has been an impressive one. The remaining people who refuse to change their views at all are impressive in a different way.
That is not what "end-to-end" means in this context. In fact, finding out yesterday that Outlook sync is not end-to-end encypted prompted me to look up OneDrive to see if it at least has that feature. It does not, and someone who doesn't know a thing or two about how cryptography works would have a hard time finding out that it does not, because the search results are polluted with people misunderstanding the concept exactly as you do.
Microsoft's own web site goes to great lengths to explain how all your data is encrypted in transit, and encrypted at rest. Their internal security and access control systems are elaborated on in impressive style. You'd think that if they're going to go to all that trouble, and want people to trust them, they would indeed provide end-to-end encryption where it's appropriate. But no, they carefully avoid mentioning the concept. They are unwilling to acknowledge that it might be a thing people expect these days, but they do not go out of their way to correct people who imagine that they already have it.
Nice timing. I don't see how warning you that your email passwords will be kept remotely by Microsoft would be "redundant." Many people will assume from that message that it would only send them all your mail, and the even more carelessly optimistic among us might guess that it would be end-to-end encrypted as it obviously should be.
The world would be a substantially better place if Signal would 1) Not require phone numbers, and 2) Allow 3rd-party clients. While they're at it maybe they could also add a volume control to the desktop client and then not push so many damn updates.
Considering that this has been in the works for a year two years already and there haven't been any reports of banks and insurance agencies objecting, your version of "it can't happen here" seems less than fully convincing.
