Most google products have alternatives. The ones with a network effect (where you need Google servers even if you have an open source client) are Youtube and the Play store (I can't get most content from either in any other way, most companies don't give apks for download), but the rest is replaceable or has open source variants (ungoogled chromium and AOSP for example).

I do agree on the accountability part. When I can't take part in normal life without a certain product, it governs people's lives and they should be held to similar standards as other governing bodies.

Agreed. I hear their Ad Words is tough to beat for those who make money that way.
