It doesnt really worsen it no. I would assume its comparable to a VPN. Because all the requests for RSS feeds come from openrss.org, it is impossible for google to individually track users. Youtube still sees the total sum of all the channels being requested but openrss.org gets the per user specifics now.

But of course. Still, you requests RSS feeds because you want to get the content on Youtube, right? So you would still share data with Youtube, but you would also have to trust OpenRSS to refrain from doing questionable things privacy-wise.

Privacy is not really an "option", its a core human right and should be considered for every proposed software solution on the internet.

You misunderstood why I replied like that. The way you worded the original comment was unappropriate, in my humble opinion, because this is not a privacy community and the tool was never advertised as being privacy-respecting but rather as a technically better alternative to native Youtube RSS feeds.
