The Inkscape's "funded development" system link leads to a Page Not Found page.
Also Bounties Network link is https://bounties.network/, without the www. With the www it doesn't work on my browser.
Can you tell which page you had the problem on? I only see links to bounties.network without the "www" subdomain (see https://github.com/PayDevs/awesome-oss-monetization/search?q...) and I couldn't find any link to inkscape - maybe you were on another list we referenced at the end?
Oh, you're right - I somehow didn't notice that I have jumped over to the other site linked at the bottom: https://github.com/nayafia/lemonade-stand
My original comment does not apply to https://github.com/PayDevs/awesome-oss-monetization . I apologize for the false information.
