They seem to think that just because a company makes non-open-source software, it shouldn't itself prefer to use open-source rather than proprietary software?! That makes no sense, of course. Specially considering the non-OSS is now owned by IBM which directly competes with Oracle on multiple fronts. It seems to me that OpenTofu is actually backed by many companies in a similar position to Oracle, which don't want to have to rely on IBM for things they have tight integrations with.
