It's a dig at those who actually do help the poor, that's how it comes across to me.
The meme: "When helping the poor, leave the camera at home."
Translation: "You only help the poor to take PR shots and look good in the eyes of others."
The meme doesn't rest on a firm foundation for two reasons.
First, as other posters pointed out Jehovah's Witnesses do very little formally, collectively, officially, for the poor, yeah, sometimes they help rebuild somebody's house after a hurricane or tsunami, but to my knowledge that's Brothers (and Sisters?) volunteering their labor and materials, I don't remember from my reading of Branch Organization (2015 edition) the Governing Body letting Branches put their funds towards that sort of thing, they just arrange volunteers to go help people displaced by the disaster. Other than that, I don't know of any "humanitarian" efforts on the part of Jehovah's Witnesses. Sure, they teach a few people English or help them learn to read or write but they don't do that as a stand alone service the same way a Unitarian church offers a free breakfast once a week with no strings attached, they offer those "services" to convert the people they help (and yes, they do help those people in small ways). The point being, it takes a lot of nerve to criticize other religions for helping poor people when the faith you belong to barely, rarely, lifts a finger to help them.
Second, we all know the Governing Body loves photo ops, I bet you good money www.jw.org right now in the Newsroom section shows one or more of them standing and smiling next to some person or persons displaced by a natural disaster. Yep, just checked: here's Geoffrey Jackson hanging out with a "sister in Okayama who was affected by the flooding that devastated western Japan in July 2018." (https://www.jw.org/en/news/jw/region/japan/witness-bring-relief-flood-victims/).
Just another person who wants to feel special even if they're dead wrong.
