Why are ad-blocking extensions so easy to come across and install on PCs, but so difficult or convoluted to install on a phone?

Question

In most any browser on Windows, such as Chrome, Firefox, or Edge, finding an ad-blocking extension is a two-click solution. Yet, the process for properly blocking ads on a phone is exponentially more complicated, and the fact that many websites have their own apps such as Youtube mean that you might have to find an ad-blocking solution for each app on a case-by-case approach. Why is this the case?
