I don't think it's sad at all. A lot of people have worked a long time to develop their reading skills, doing free readings for years and finding out what works for them. After all that work, wouldn't you want to get a little something back for your trouble? Especially if you're making money on something you enjoy.
I agree that there are a lot of people out there who only use tarot as a way to rip people off, and those people really make me upset. They give people who read tarot a bad name. But that's different than developing your skills and feeling ready to start charging for readings for the general public. It's just like someone going to a college or technical school to perfect their craft, then opening a business so they can start making a living off of it. Some are going to cut corners and are just in it for the money, but others love what they do and want to live from it.
Money has always been a big deal. People have been making money off tarot and all sorts of fortune telling and mystical things for dozens, probably hundreds, of years, so that's nothing new. We do, however, have to adapt to the times. Thirty years ago there were no online services, and ten years ago there were no apps. Everything evolves; society, tarot readers, and jobs as a whole, so I see no reason why people shouldn't find new ways to make a living or just make a few extra bucks doing what they love.
But that's just my opinion! I respect that everyone has different ones.
