Thank you for writing this. As much as I love conspiracies, I'm not that full of myself to think this CEO has nothing better to do than to stalk some random German guy's MASTODON account. The sad part is that this was just bound to happen sooner than later, even to someone who recently criticized Oracle.

and a longer explanation of his thoughts (mostly that Oracle has left him in the dark so all he can offer is conspiratorial speculation)

Anyway, since Oracle won't say, it seems fine to take adverse inference.
