I’d be more concerned as well if this would be an over-night change, but I’d say that the rollout is slow and gradual enough that giving it more time would just lead to more procrastination instead, rather than finding solutions. Particularly for those following the news, which all sysadmins should, the reduction in certificate lifespan over time has been going on for a while now with a clear goal of automation becoming the only viable path forward.
I’ll also go out on a limb and make a guess that a not insignificant amount of people only think that their “special” case can’t be automated. I wouldn’t even be surprised if many of those could be solved by a bog-standard reverse-proxy setup.
That’s a bummer. I’ve been using the forked version as well, and even that dev has been annoyed with Google Play enough that it’s only released on F-Droid nowadays.
Personally, I don’t think it’s an issue only releasing only on F-Droid, because the people interested in Syncthing wouldn’t be deterred by that if they’re not already using it, but I totally get why that might sap the last bit of motivation the dev has.
