You can open a savings account with Langley CU and get a free EQ FICO 8 Classic with them.
Many people have a Citi card and get a free EQ FICO 8 Bankcard Enhanced with them. It's not exactly the same model as FICO 8 Classic but it it is still more than adequate. If a person actually wants to compare the three bureaus using the same model it's a bad idea anyway to use credit cards or CUs, since the scores aren't being drawn at the same instant. The best approach for a 3B comparison would be the $1 trial with Credit Check Total.
Penfed and Navy Federal also offer Equifax 9 scores.
PF would be for anyone willing to donate and Navy would require ties to Military.
Possibly could be others out there.
And CGID also showed the score site.
