I've added a mention of the client in the text, good point, thanks!

Do you mean if one of the website is paying for being linked here?
If I understand your question correctly, then the answer is no. Actually you can assume no link on bitcoin.org is (or has been) generating any kind of income so far to my knowledge (except the Foundation sponsorship banner of course, but it's clearly stated).
If you think any link is worth being replaced by another or anything, feel free to open a pull request (preferably only if you believe there's a good reason in doing so, because updating all translations is time consuming).
