Why are you paying for weather
I don't think a VPN counts as SaaS, it's something that costs the company money constantly to run, SaaS is more like the Adobe apps, which are not a service at all and it doesn't cost them money for me to not uninstall it.
Adobe via my school, I have no choice
Clock app set many alarms
The things you say you want are the complete opposite of lemmygrad (and hexbear). I'd avoid lemmy.world, apparently the mods there abuse their power, and the fedi is meant to be spread apart, Lemmy.world is getting a bit big. I don't see why you should go to a Lemmy instance specific to politics, but the only ones I know of don't follow any of the things you want. I'd say to join a general purpose instance, maybe one in your country? Or you could join a topic specific instance like the programmer one and the various star trek instances.
That is very stupid
If it's an internet service that should be one, it's not SaaS. I'm not redefining it, that's just the definition. SaaS is just software, but as a (subscription) service.
