Famous Players Have Better Luck

About
Some say that in Pokemon GO, famous players such as YouTubers and Twitch streamers are given better luck with things like Shiny and high IV Pokemon than the average player in order to attract more attention to the game. If proven to be true, this would be very controversial, as the community has never been on good terms with the game's publisher, Niantic, and this would possibly start another wave of people leaving the game like with the HearUsNiantic campaign in August. Another interesting thing is that Pokemon GO has never disclosed rates for encountering Shiny Pokemon with anyone, which makes it harder to find out if the myth is true or not. Studies by The Silph Road have shown approximate rates, but it is still possible these are incorrect.

Conclusion
Because of Niantic's poor communication with players, it is difficult to find out if this is true or not. On one hand, it would seem tedious and useless to manually change rates for every Pokemon GO account that was run by someone well-known, but on the other hand Niantic has been known for doing this before. For example, in 2020, a popular YouTuber by the name of Trainer Tips said that he would not be participating in the Mr. Mime Special Research event, because the ticket was too expensive for the reward it gave. However, on the day of the event Niantic put the ticket into his account without him needing to pay for it. Before this incident, the notion of a game's publisher boosting certain accounts seemed ludicrous, but now that this has happened, it would not seem surprising in the slightest.
