There are tons of projects with "supa" as the prefix, both related and unrelated. If Supabase were going to take legal action on this, they would have already.
Fwiw we wouldn’t take legal action but sometimes we politely reach out if the name could cause confusion for customers - everyone has been very amicable and usually it’s a win/win to rename anyhow
its jut not a good starting point for any yc company so might as well rename now while its cheap
i dont speak for them but 100% this is close enough to home tjat they should be concerned
