The decision from the Commission lists what the US did (linked from the article).[0] Although, I'll admit, I am not great at reading language that verbose.

A short check tells me that any current or future president can revoke an executive order at any time. So, the commissions decision in regards to FISA (which this is mainly about) hangs on Bidens word that neither he nor one of his successors will change it? Yeah ... I don't see how that's gonna fly with the EUCJ.
(The article also stated it, but I wanted to check in the original documents if that's really all they base their "all is good with FISA now" decision on)
The certification is based on Principles outlined in the document and are very GDPR-ey
... none of which are European, or much aligned with European interests in any way
I call BS.
