SUSE was sold to EQT in 2019 and went public in 2021.

I stand corrected, it is still owned by them in 75% though, and apparently they are an investment fund.

Sometimes I feel that a lot of tech companies are virtually behaving as hedge funds

Do you have a source for that? I was under the impression SUSE no longer had any ties to Micro Focus

Wikipedia?

Are you confusing EQT and Micro Focus?

    SuSE is owned by MicroFocus.

As per the Wikipedia article, EQT still owns 75% of SUSE, not Micro Focus. Micro Focus is no longer involved with SUSE
