Their published study appeals to scholarly acceptance and comparison of manuscripts, including early witnesses. That is their stated reason for the choice; each reading still needs examination.
Hort’s hostility toward the received text is plain in his own words. In the same letter, he welcomes changes supported by manuscripts and the availability of early witnesses.
Did that hostility affect his decisions?

No. A Greek edition concerns which Greek words are printed. Translation concerns how they are rendered.
