Colombia didn't have it 'taken' from them, they told FIFA they were ****ed and wouldn't be able to host it.
Uruguay-Argentina-Paraguay is the only bid that has been confirmed for 2030 so far, the only other rumoured bid out there is England or a possible UK bid, and that's not even official.
The idea of Uruguay being one of the hosts in 2030 kind of makes sense, as they hosted the first one 100 years prior. The fact they are involved in a bid is of no surprise.
It's going to become more common to get joint hosts as the tournament costs too much for one single country.
