The nice thing with most Google apps is that you can get your data out easily with Takeout: http://googlesystem.blogspot.com/2015/08/export-all-your-goo...

If not, then do you have the same fear of any new product from any company? That risk is there too...
My debit/credit card pairing hasn't been cancelled or changed in the 10 years I have had it unless I have specifically engineered that change.
The reality is that you just shouldn't trust google for anything that appears long term, and consider them as a casual partner, not a long term relationship.
I am perfectly fine with people saying that Google, a multi-billion dollar corporation, cancels things less often than a company with a completely uncertain future and no profit.
I am also fine with saying that comparison is not fair to the startups or to business that try to deliver a faithful product to their customers.
I think there's a phone interface feature associated with Google Hangouts. ("Google Hangups?") But it probably requires that everyone you talk to have a Google account. All these little closed-world communications systems are a pain.
The dedicated Google Voice app has withered, but Google seems to be integrating the service into their other projects.
Er, it's a phone interface. It makes phone calls. Everyone you talk to is only required to have a phone number.
"Hangouts remains the future of Google Voice, so we’re going to keep bringing the most-loved Google Voice features into the core Hangouts experience,"
But I really wanted to try it out anyways -- with number portability there's just not that much risk.
Now we have Google, that's almost as big but not as contentious, and they're canceling things left and right, and that's causing problems too. So now I'm not sure what my position is on the topic.
Perhaps they need to unbundle.
Google Wave works great today on self-hosted platforms.
But what would you take from Google Wallet? The physical debit card? The payment service? Unless you're opening a bank, I'm not sure how useful any of that would be.
