If you have GSuite, it seems you can whitelist existing applications. I've done that with SMS Backup+, so it should keep working for me. At least that's my understanding.

I suppose that people on the consumer side probably don't have that option, and it's probably not enough to get people to start paying.

I already pay Google as a One customer. Does GSuite have a (possibly not presently enforced) five user minimum?
