Watch
Star Trek: Enterprise episode, In a Mirror Darkly ( parts 1 and 2 ), and you'll see what I mean.

Indeed, I thnk the whole issue is that despite there being 'con Fems, that what little spotlight for fembots in the francise was given fell to 'bots.
As far as G1 goes, including Japan, and the recent Go-bots additions there are 20 named female Autobots (including Minerva, technically more of a headmaster) to 7 named Decepticons of which:
Clio: never existed beyond a mention on a letters page in a UK comic.
Crasher: Retcon edition from Go-Bots
Nightracer: Botcon exclusive
Esmeral: Victory. Wife of the Decepticon leader Deathsaurus
Lyzack: Victory. Sister of the Decepticon member Leozack.
Flip Sides: e-Hobby special redeco of the Eject/Rewind, Female by way of bio. And a pink paint job.
Howlback: e-Hobby redeco of Ravage Female by way of bio.
Not a roaring endorcement for an unseen network of female Decepticon existing elsewhere, thou the addition of Go-bots does mean there should be a few more. Add Universe/Timelines and The bots get 6 more, while the cons only get 3. and The Beast wars adds 5 to each side.
Not even touching the Unicron trilogy as Thunderblast is the only con while the autobots get Override, and new copies of Arcee & Airazor with a number of referances to others.
All in all, with the exception of Animated where things are currently even, the Decepticons have kept their Fembots to unseen references, unknown storylines, and retroactive additions. No wonder there could be a belief that Megs would have trouble with them or be getting rid of them.
Sad really, seeing since Arcee was made a central figure I expected that a female 'Con would be introduced as a "Baroness" to Arcee's "Scarlet".
