Yeah it’s all speculation. The author basically ran a follow up to another article, which they acknowledge, which was a poor translation of a different article. The whole thing is like a journalistic centipede funneling shit all the way down.
Like why start the article with a line like:
Windows 12 rumors are just that ... rumors.
And then run an article with even more rumors. I get you can speculate based on trends, but this just seems to be written just to generate clicks from a hopeful Linux community.
