Alright, thanks for the reasoning!

This was one of my very first public shaders, and I continue to update it, recently ported to Android, iOS and Mac.
I know for a fact that there are free alternatives nowadays, so if you look in the right places you might find them.
What I could do is decrease the price a bit, just so I keep some passive income, which is quite important to me.
I have some free shaders available as well, some are on my Patreon/Ko-Fi, perhaps I should also publish them here.
As for the pricing, I can do a price cut, specially since it's been a while since this particular shader has been sold. Hope that helps!
