Syag, I don’t have insights in how sefaria works and they ain’t “my guys” in any sense. I use it to look up basic commentaries and references and never found an objectionable rishon or acharon there.
I saw that they have open pages for divrei Torah, I presume they do not police those, so I won;t be surprised there will be something bad there.
How they dress indicates who they think they are. I saw Reform ladies in kipot but not in tichels, but I am not up with modern fashions. Could there be some militant feminists or OO? Possibly, I just did not see.
As to “new paths”, I am all for old paths as much as possible. Everyone now is on new paths, though, whether they wear a shtreimel or a modern jacket. Rambam wore neither. And we here discussed enough Rambams that are not followed in “frum” communities – all with good sources, but they are all “new paths” that Rambam would not recognize or be upset about.
