That would be difficult to do, if say all banks decide to only support Windows/MacOs. My bank that I use is a bit wonky on Firefox but works fine on Chrome.
Some banks even refuse to run on Firefox.
Also, switching banks might be more difficult than switching an OS.
And you would lose the reward points if any if you switch a bank, not to mention, if you use autopay that is configured to withdraw from a certain card, you would need to go and reconfigure that everywhere.
It is not technically impossible, it's just going to arduous.
