That situation raises a separate set of concerns, especially in the context of Microsoft's main database cash cow being SQL Server, not Postgres/Citus.
Yep, exactly. Apologies, my previous comment was semi-sarcastic but in retrospect that was way too vague :)
On average, HN leans anti-MySQL, with concerns about Oracle ownership frequently cited in these discussions (mixed in with some historic distrust of MySQL problems that were solved long ago). But I rarely see the same sentiment being expressed about Citus, despite some obvious similarities to their ownership situation.
Personally I don't necessarily think the ownership is a huge problem/risk in either case, but I can understand why others feel differently.
