FOSS cloud apps aren't subject to arbitrary shutdowns or unwelcome changes to the ToS. This is a huge, obvious advantage that most cloud app users don't realize. I think supporters of FOSS cloud apps should have something concrete to point to that shows the fragility of proprietary cloud apps.
However, I would not use this website as a reference for the following reasons:
- No citations! It reads as if it is pure opinion without any citations.
- It's hard to find evidence for some of the claims. Google+ shutting down? Is that pure speculation?
- No place to discuss app status in the app. Comments or a wiki should be offered.
- Closed source, no way to send pull requests for updates/corrections.
The page has a prominent link to the author's Patreon. This comes across as litte more than link-bait to draw traffic to the Patreon page, and a hit-piece on Google. The potential benefit to cloud app users gets lost.
