I am glad that we came to appreciation of what these companies provide.
We often tend to think that “baalei tzedokah” are only those who donate their money to worthy causes. Does being paid for doing a mitzva makes it less of a mitzva? We allow even taking money for teaching Torah, so kal vehomer, anyone who does a mitzva of heeling people, helping people take cheap vacations, buy online goods desreves our appreciation. I think it is Ben Azzai who contemplated how many people are involved in making his breakfast? So much so in our time, when right now someone in China is packaging something you are going to buy tomorrow.
