I don’t mind it if the game was always free to play. They gotta make their money somehow if that’s the case. The problem I have with Overwatch and the microtransactions is that they went free to play after they already made a fuck ton of money off of loot boxes and the fact that you used to actually have to buy the game. It’s just a cash cow and gameplay (including matchmaking, like you said) has suffered considerably. Not only that but they charge as much money as entire games for skins. Games like Overwatch when it first came out.
I don’t mind microtransactions in free to play games, I really don’t. It’s just the method they are using is just blatantly greedy and targeted for whales that will pay anything for fear of missing out.
