I would consider this move. I just assume no one has ux even close. It would take me at least a year to fully transition from one gmail address.
If anyone has suggestions I would be really interested in hearing them.
For example, for web-based services, if you don't want something to go away (or be abused), then your best bet is to run a fully open source implementation of that version on a VPS (VPSes are on computers owned by others, but they are cheap commodities that you can easily replace, replicate and, if necessary, move to dedicated servers or your own machines). Personally i'd also only use simple applications with little to no (preferably no) external dependencies in case i need to pick up the development myself or make modifications.
(of course having said that, i generally avoid web-based applications altogether and instead opt for desktop-based solutions whenever possible - one major reason being control)
Being owned by a major is bad for life expectancy. Being bought out by one is worse. Google are quite probably the pack leader for shuttering services for no obvious reason (Reader etc) and also buying startups to shutter them or turn them into something unrecognisable.
I try to apply this view when choosing all products and services - I'll favour startup and family owned over multinational brand for everything from SaaS to food and clothing and often pay extra to do so. I'd like to think there's still a chance of individual customers mattering to them.
I also favour desktop where possible.
Here's my main problems with google and why I've been trying to get away from them as much as possible.
1. Very poor quality customer service. They might have better customer service for things like adwords (I wouldn't know) but as far as everything I have experience with (business services, google cloud) my experience has always been horrible - good luck getting in touch with a human.
2. (as you mention) A high level of insecurity about whether or not a google service will actually be sustained or whether they will drop it and leave all their users hanging to go try out their next big idea.
3. IMHO unethical business practices, mainly when it comes maintaining their monopoly and violating copyright laws [1].
4. The fact that they control so much of an ever more centralized internet. Regardless of however benevolent one may think they are that much power concentrated in the hands of any one entity is likely a dangerous road to tread upon and one I'd rather not risk going down.

I would also never use the sentiment shared on HN much for anything, half of the people here have a stake in their own little proprietary technology they want you to sell :P
