This is a no-brainer. Sefaria was founded and is run by people who are completely or almost completely irreligious. They have no reason to follow any standards of tradition. For a long time already they have had Kfira on their site. They link to Kfira sites, their Mishna is translated by a conservative guy, their Yerushalmi is translated by a totally irreligious person etc. etc. and worst of all they never link my blog or shiurim. What do you expect? It is only going to get worse as they expand.
The article says "Although there are no confirmed report of Rabbis officially banning Sefaria...." actually there are. The Chumash [written by a VERY VERY BIIIIIIG RABBI IN THE SKY!!!] when it forbids Kfira and so the Gemara, Rambam etc. etc.
I would recommend to substitute mg.alhatorah.org and shas.alhatorah.org and the many other sites within those sites. It is a tremendous resource and run by a Yarei Shomayim/Talmid Chochom/Genius whom I know personally. Now, this site would definitely not get a Haskama of a Lakewood type Rosh Yeshiva or Gadol [e.g. he features the Chumash commentaries of various maskilim alongside classical commentaries] but it is certainly better than Sefaria.
You want complete purity?? Not on line..... In the Beis Medrash and in the Beis Medrash alone.
