The drones are coming

"Google is far more trustworthy than my ISP and has far superior uptime."

Fat lot of good that does when you ISP is down. Tell you what, my PC has better uptime than Google, and I don't need my ISP to open my files. But hey, you're free to lock yourself in whatever scheme you want.

"Google is free for life."

You don't know that. Google is ad-based for now. Web advertising is going down the crapper, so one day Google just might decide that you have to pay to access your precious online storage.

And whatever happens, you might end up regretting having entrusted all your personal files to some entity that can change its TOS on a whim, and hand over whatever data a given government wants.

If a government wants data off my hard disk, they'll have to come and get it first. It's called privacy, and as soon as your data leaves your door, you end up saying goodbye to that notion.
