An adaptation is not a contradiction, everything else is correct. When it comes to contradictions usually we talk about things that are current or don't make sense, you can't just pick any point in time like find something I said 20 years ago and say look you are contradicting yourself now. If you do that, then you are rejecting any learning process in a biased way.
The thing is that I don't think that there is any adaptation nor learning process. I think Saylor knew from the very start that eventually Strategy would have begun to sell Bitcoin.
Simply, the "I will not sell any Bitcoin" was a slogan that was useful for Saylor in the phase his company needed every new investor to grow. Now his company is one of the biggest Bitcoin players, growth isn't that important anymore. And perhaps there is also some "maturing" of a part of the audience. The "brute" Bitcoin Maxi from 2018 looks a bit outdated in 2026. But all this was predictable.
The little uptrend we're seeing since 60k was thus probably the perfect occasion to change the communication strategy and admit that selling is on the table.
So I can fully understand people who feel betrayed now. The thing is ... that's simply a very typical move of a "growth company". "Fake it until you make it" often works

(and don't do it like Elizabeth Taylor ...). And, as I wrote, if Saylor sells or not, is not important for Bitcoin at all.
