I'm not sure if people are turned off, I just think that these days, people have very little disposable income. I know when I decided to go all-in on Splinterlands, I reallocated my entire gaming budget to SPL and even started selling off portions of my MtG collection for SPL assets. As the world plunges deeper into authoritarianism, conflict, and financial chaos, there is going to be even less money to go around.
I continue to push on the advantages that make Splinterlands great: transparent blockchain print rates, trustless card renting, and digital ownership. But MtG has ALL of this (besides the true digital ownership) through the original Magic: Online client. Most of them still enjoy playing MtG. I never stopped enjoying playing MtG either, I just didn't have a community I could meet and play with regularly, so Splinterlands became a great option.
There is also the hurdle and desire to learn a new game and take on a new challenge. Many are unfamiliar with Web3. Most people just aren't in the place where they want to give up on MtG the way I did. I won't stop trying though!
