Just as they did when all the snafu with Dropbox and the switch to a subscription based service.

Before the subscription service, I had spent hundreds buying all their apps for me and my family. 1P wasn't cheap but it was worth it. They used the users' Dropbox to host the web based vault. Obviously one day Dropbox decided it was not ok to use the public folders to host websites.

It really was a shitstorm in 1P's forums and they handled it very badly.

1P could have spent pennies hosting the vaults on S3 or something but they decided to tell their paying customers to switch to the subscription if they wanted a web based vault. They didn't even have the decency to offer a free year to the subscription or something.
