This seems to be the lesson of Google. If you depend on the service, find someone else and pay them. Too many services are decommissioned, and if they are replaced it often is very different. Outside of search/email, it is a risk
The uncertainty is the problem. Until recently I had fairly slow broadband, weeks to sync initially. Changing providers is often do it again, loose history either way, or pay another provider per GB to do it.
The lack of official Linux client was the killer for me years ago, but prior to fibre internet the uncertainty was a big issue too.
People want to plan around services like this remaining. Nothing is certain, but the news quite often talks about Google dropping another service.
