Does anyone know of any sport that has been introduced into the olympics in the last 50 years where the existing participants in said sport have been adversly affect to the point they can no longer enjoy their chosen sport?
Plenty of sports have fought long and hard to leave the olympics.
Baseball fought for over 100 years to get out of the olympics, they finally were able to do it for 2016 in Rio.
Baseball never liked how the olympics would be on right in the middle of american baseball season, of how other teams would say they were the best in the world instead of the world series being the best in the world, MLB hated the petty olympic politics, they hated how the olympic games did not follow MLB rules
Golf had the same sort of issues they didn't like how the olympics would detract from their main circuit of tournaments, but it will be back for 2016 over the objections of pro golfers.
Most sports of course love the olympics gives them a chance to rebrand their product as wholesome instead of thuggish
