Thank you for linking the article!
i understand your reasons why krita material should be free mostly. Thank you for explaining why.
I would like to explain my thoughts too. I think value is associated with money. people who try krita and go
“Wow, this is actually good for being free!”
i think they have a misconception that krita cannot be any good because it is free. who would give away access for the amazing program krita? 
i think paying for a few materials each year will not be much as photoshop subscription. some people might move on to csp but that is okay. there are some people who really love krita and will like material. also we have special engines they dont have
unless they 'borrow ’ idea from us 
i think money holds hands with the word professional. if someone put a lot of work into beautiful brushes i will like to buy to support their efforts. or if i really admire the artist and the style.
i love krita for being free but i think it can mingle with money too. like the development fund, good things can come from it. we can add value to krita 
it might sound shallow and mean to say money is associated with value but i think that is the sad truth. with this new society it is like this
well not for everyone but maybe a bigger part… when I began to see people want the newest apple, brand clothing and shoes i realized. it is not their fault, the world has made some people change a little. value is hard to measure so people decide to use money to measure 
i also see this pattern:
the scenarios are associated with money in a way. But there are other types of value, like exposure.
- person with large following uses krita. Audience goes ??!! and they will try it because they admire the artist.
also
i saw a recent reddit post that said they felt they couldn’t make good art because they didn’t have a good software like csp or procreate. then they really tried and saw how good krita was 
i think because procreate and csp are associated with money it is consider more “elite” money has a odd effect on people : (
i am sorry if i offend the krita community and developers by bringing up money. i love krita and contribute my thinking in a good way.
so i want to say in short that money appeals to some people and that having an area where people can see some paid options might be good.
i think paid links can go to a third party site like gumroad or etsy. but would having the option to see paid stuff with free stuff be so bad?
some might say “omg all the good krita brushes are not free” …well most good things are not free because effort needs some value (like money). krita is free but not free because there are people supporting the developers. There could even be special material for fund supporters only…
most brushes creators for krita do not charge and love to share presents and tips to make more brushes too. there is also the young art community that is thriving. they constantly go “what brush did you use” and the other artist gives them away for free. the young art community likes to share stuff too.
a site like krita market will make sharing a little easier and browsing easier. i think there will always be people who will find hateful things for krita. Like how some people start hating blenders changed ui or YouTube’s annoying Shorts videos.
i apologize if I offend anyone with my words. ty for reading.
even with an area with only free listings i think krita community would be okay with. but paid listings (with links to other sites) might be okay too…? let me know your thinking thank you
edit: when I said add value to krita i did not mean to say krita is worthless without money. i see krita with value in the bright community and amazing software. money just may bring new opportunities. the main thought why i bring up money because I looked at blender market. blender is free but i dont see people hating on the paid textures (or dont see too many). do you think people will really hate paid stuff?
if so then just a place to share and download free material is good too.
