Lots of “source available” licenses have a clause that a few years after development stops it becomes open source. Thing is, software with those clauses have existed for years now, and I dont know of a single case where it actually came into effect. Its very easy to have a minor patch every four years to prevent the license change, and if the devs of the software actually wanted to open source it, they would have done so whenever they wanted instead of only promising it. Clauses like that are supposed to combat abandonware, but abandonware does not usually happen because someone forgot the software existed, its a conscious choice to not release the source.

Never tried it on desktop, only mobile, but Organic Maps is really good and has a desktop version

IzzyOnDroid gets their packages by searching for Apks on github in a semi-automated manner and does basically no filtering on its own, so there may be low quality or malicious apps on there.

IANAL, and a bit unsure about the following information, but I think you do need a privacy policy if you process someones elses data(like for example their login data, private messages, etc) You may also need an Impressum when hosting the official website for the bot(germany specific, maybe look it up if you actually need to do this)

I dont think you need a TOS.
