This is just a bunch of lies. I was just at a Greek Church last week, Greek Churches are stereotyped as being the most ethnic and unwelcoming of converts, and yet this Parish was overflowing with a growing latino convert community. Charity work happens all the time. My Parish consistently helps with supplies and funds for our local homeless shelter and meals for low income families in our community. My own Priest doesn't take a salary and uses his own personal funds to provide for our Parish community and the needs of our surrounding community. I personally raised over 10 thousand dollars in assistance for a ROCOR Mission.
I'm sorry to tell you they just don't help anyone at all. Their churches don't do charity broadly speaking. Maybe they do one charity event a year maybe. Their churches are ethnic clubs and the money goes back to the old country to pay for people there. Ortho is not the answer.
