You can keep speculating about some conspiracy, but I do not believe in your line of thought based on the facts that I know. This is not new, it has been in the works for some time and I guess the effective date happened and now they don't want to do any trades with OTC stocks. The way it worked with OTC stocks was different than trading on a major exchange, which you could do on their website. OTC stocks had to be called in and then wait to see if you got them at the price you were hoping for. With the added interest in US stock market post Covid, it became a hassle and because of the process they got a fair amount of complaints. It wasn't that it wasn't profitable for them as they charged a large fee for these transactions, it was just that it took away resources and banks have been trying to cut overhead since the interest rates went up. That's what I was told, but you do you and push a conspiracy theory.
