I personally don't go on the "ruined my childhood" thing and I hate it too. And if anyone makes this claim I'll join you in shutting them down. The funny thing is that when some fans see something in a new continuity that they don't like, they claim that it's "ruined" G1. Yet when the opposite happen, nobody makes the counter claim.
e.g. no matter how awesome IDW's G1 gets, nobody claims that it's "enhanced my childhood!"

The only way that someone might do that is if the story is in continuity with G1 and is officially retconning it - as happened with BW and BM. And BM was the first to cop a lot of the "ruined my childhood" hate (Bob Skir even copped death threats from fans ). One main source of this vitriol was BM portraying Cybertron as having an organic core. But Bob Skir didn't make this up - it originated from G1! In the Marvel Comics, Primus crashed into a rocky asteroid which he then reshaped as Cybertron. It also showed the original inhabitants of Cybertron as being a technorganic looking race of Demons who dwelled in Cybertron's Underworld. Both the G1 comics and cartoon showed Cybertron as having a breathable atmosphere. IIRC Transformers Prime was the first TF story which showed Cybertron as having an unbreathable atmosphere. But the G1 comics showed Cybertron having an organic core, even with water (deep enough for Seawatch to zip through in boat mode, dragging Bludgeon along for the ride!). The G1 cartoon episode "The Dweller in the Depths" showed that Cybertron had an organic core in the G1 cartoon universe, and that the Quintessons' first creations were the technorganic Trans-Organics. So Beast Machines was actually being canonically G1 accurate in showing Cybertron with an organic core.
