I agree that there shouldn't be a stigma against licenses that aren't FOSS. There's no shame producing software that's not open source, and if you're open about it (ie not calling it FOSS if it isn't), sharing it under a different license (such as the SAMS licenses you mentioned).
Today "open source" is often a marketing term (if any proof is needed, see LLama :), often "let's build a community of users on our discord as a loss leader into our startup sales funnel" term, and ... in a very few cases .. "let's build together, rising tide lifts all boats" thing.
Disclaimer: I'm one of the people behind that model.

Agree that if non-lawyers (or corporate lawyers with no experience in open source licensing) craft something, they might regret it down the road. Better to pick and choose between now plethora of available options.
I would just prefer to have more liability protection.
Would be curious what you have in mind. The FSL comes with a default no warranty disclaimer.
For why, see questions 33-36 at https://yzena.com/yzena-noncommercial-license-faq/ .
(Also the fact that this license was not written by a lawyer in itself seems … less than ideal)
But I have actually gotten halfway with a lawyer. A lawyer actually wrote the No Duty clause.
