It's an attempt to revive this dead coin, but it's shooting on foot.
The developers have nothing but trying to give customers some free money to keep buying that currency, so they may make some gains in the short term, but in the long run, Bitcoin ABC's project is dead.
Many projects are revived that way. After months of dead, they make swaps to a new algorithms, new chains and attract new investors. They do it in bull trend and after take profit, their projects will be dead again when the bear market comes.
A quality of one project depends on a core team and such project does not have a good developer team. Calling them as scammers or not, it depends on each person, but they are not good and productive developers.
