both of those are either estimated or anonymous sources

not credible

Well they are a private company so you are going to have to evaluate it on that basis, but reuters is generally considered credible.

well that would be good if Reuters were the source of the figure

but they're not, they're simply reporting on what SimilarWeb has estimated

and that estimate is essentially based on nothing

Are either of those things indicative of "fastest growth ever"? Maybe 100 million users, but we live in a world where it's hard to know how meaningful that is (ie Tucker's X videos getting 300 million views).

MrBeast[0] has about 182m subscribers, and it is probably easier to get a subscriber on youtube than a user.

Views are easy to inflate, I wouldn't even consider it in the same ballpark. This video[1] of Vivaldis 4 seasons has about 1/4 billion views.

The shortest time to 100 million users is almost a definition of the quickest growing company.
