They are, but many of them are difficult to make.

I've been learning PHP here lately. It's not an easy language to learn.

To go through all the learning, struggles, and time you invest in creating an addon, you should be able to earn a profit from it.

Right now in the States, you can sell a simple family home for an easy $100K, but if someone tells you that they'd rather pay the old cost of $60K instead, you're going to say no if you're smart. Someone else will buy it for $100K.

Market share and use is going to drive up the price of things. It always has.

More people use XF and want those features, the more they will have to pay.

Actually there could be a market for paid mods for free software. Think about it. The software is free so all u pay for is mods vs paying $200 for software, plus paying for mods ( and themes).
