Well there you go, 2 statements that we all knew would be getting issued at some point because they said otherwise a couple of days back, normal for Thailand, say something 1 day and say something opposite the next.
I finished my quarantine last Friday. I did it because I live here. I cannot imagine a "tourist" going through that, or even 7 days of 'that'. In reality I don't expect them to open up in a meaningful way this 'high season'. Maybe 2022 will be better.
