Edit: i dont know how many people feel this way, I beleave this and heard (verry biased, right to repair) people say this before.
Probably confusion but also abuse of the buisness model. “As a service” implies the recurrant payment is due to the service costing them resources to keep running. People like Adobe are just rent seeking. Also, the idea of ownership vs renting gets blurry.
Your examples, altho I havent thuroughly looked through them all look to be doing “as a service” correctly
Wow, yes!
My personal niche, Sbubby was pseudo migrated many diffrent places, 2 discords, a lemmy page and someone is still running the subreddit.
There was a explosion and resession, there is no hope of finding either discord without their link and the reddit mass exodus was temporary were left fractured across 4 or 5 sites.
My other niche, on the reddit side is filled with horny people and salesman. Over here, theres a ~4 user/month community thats sweet and loving but has nobody.
