Which sort of pundits? You said "pundits...their monopolies". Are you referring to people with a vested interest in the companies/monopolies? If so, that makes sense. They have no reason not to say that, whether they believe it or not.
Yes you're right. However on HN and similar tech/geek areas, the common theme regarding FB for a decade now has been direct or indirect implying of its coming demise. Which was what I was saying in my comment. Those people are not correct. It is being said in this thread and other recent threads too. If FB is still a $5-600B+ company in 2025, then these recent comments are also not correct.
Which is to say, it's hard to imagine FB dropping lower than the ~11th biggest US company and ~15th biggest worldwide[0] company at a $600B market cap in 2025. A valuation they did not cross until May 2020.
[0] Right now they are 8th in the US and world. Top 5 for earnings. Usually 5th-6th.
