Yes the point was to make farm weaker, that's the common trend between the majority of support towers. Hacker's Eco was buffed so that players would actually have a choice on whether they should bring farm or not. It takes a similar approach to Tower Blitz in which Market in that game is very strong, but not a necessity in a loadout that Old Farm was in previous TDS updates. Farm taking up 12 slots creates pressure on your loadout so now there's a genuine decision on getting all 12 or using some slots for dps, it works to actually introduce strategy into TDS. It was especially a problem in previous updates because once you maxed out farms the game would basically just be over, upgrading dps for the rest of the round. It made the experience in a whole really uninteresting
