I thought mateschitz will/estate ensured "RedBull" could continue to operate in f1 for a while yet. Happy to be corrected if anyone knows thats not correct.

I mean that's just a blanket statement to reassure everyone's future as they put a new management structure in place.
Thinking logically at this there's a cross roads that's coming up for all private owners of F1 teams where they could be sold to interested car manufacturers, we've seen some of that activity already with Audi and Sauber. The value of an F1 team will be no higher than where it'll be between now and 2026, so it would be a realistic time to sell. The Red Bull F1 project has been driven primarily by Helmut Marko, who at 79 isn't going to be around for a long time.
The first steps was that partnership discussion with Porsche, if Red Bull weren't even interested at selling the team then they wouldn't have entertained the discussion. The difference as to why the Ford discussions gathered pace was that they had no interest in putting any of their management team into Red Bull Racing unlike Porsche. Combine this with F1 aiming to move to net zero by 2030, increased growth and awareness in America, and a team that they have intimate understanding of after selling it initially to Red Bull back in 2005, it makes absolute sense for Ford to buy the operation. Red Bull then move to become a sponsor of the team, and they manage to exit and focus on what they specialise at; marketing.
This isn't just a Red Bull only thing at the moment, I expect a Williams partnership/sale to happen soon as Dorilton look to exit.
