Honestly, I'm so concerned about how bad the monetisation has got in GO this past year. Since the Colossal Discovery ticket event, there have been more and more pushes for financial purchases. Ticket events each month
Then there have been the egg events in high numbers

(1/?)

...as seen with Dragon Week, they've dangled shinies in front of people and make them locked behind eggs with barely any hatching it.

Remote Raids lacking a free component (until complaints happened) is another thing, and once the mechanism was added, they pushed it hard

The removal of bonuses to get people to buy Incense (which then got hindered) as well during these times really concerns me.

Sensor Tower recently reported GO had the most revenue in 2020 of past years. No kidding when you look at how much it has increased

There was also a report from Sensor Tower earlier this year noting how the userbase had dropped to around 10-15% of 2016 levels, but the revenue is higher
I really enjoy Pokémon GO but my word this past year the shift to the monetisation has been, for lack of a better term, gross

Also, one more thing.

We SHOULD see the rates of hatch from eggs and shiny rates for raids when we put money into it.

Every single other Pokémon mobile title has shown the rates, even when they didn't need to, and it's really bad GO doesn't
