To be absolutely fair, they're doing this across a bunch of different series recently, so it's more like they're mass-releasing chapters than they're trying to re-snipe their old stuff. If they were doing this every month I would understand but it's really been this month, across multiple series. Some were picked up after they went on hiatus but some have not.
Now, all that said, it's not the best optics to do this kinda thing on series that have been picked up by other groups after half-year hiatuses(hiati?). I'm kinda torn on this; I wanna be mad at LH, but they're still current on a ton of stuff that I read. And again, it doesn't look like they're targetting stuff that's been picked up, but instead shotgunning a bunch of series and hitting a few that have been picked up by others in the process.
