DM recently hit 2000 (currently out of 2085) patrons and I wish that number would not decrease anymore. After all, if you've read his patreon , you've seen that when the 2,000- patrons number is hit, FB updates will come out more often.
Don't worry...
...if you check today the patreons are 2109.. more than 20 in just 2-3 days is not bad specially at the end of the month (there will be no new realease in March so the new supportes have to pay again for April... sharing the Extra does not affect the number of supporters...
option 1) in internet there are people that have money... they will buy the media they love to play... even if there are cracked version.
option 2) in internet there are people that have NO MONEY.... they will never try to buy nothing... they will always looks for cracks.. the people of this second option will never be able to support any game... they will use only cracked software.
the team member you mentioned always write lies here

increasing or decreasing patreon supporters is not affected by the time of sharing of the "cracked" release...
All developers here are happy to share because this site is one of the most important for make more supporter...
(maybe only DM complain about that...)
I've never seen a DEV complaining about this... except for DM
