Here is a video from Comic Drake. While he makes no explicit reference to Comicsgate, his reference to "fan rage" makes me think he is obliquely referring to those in the movement when comparing Riri Williams to Miles Morales.

While he addresses some of the criticisms about Riri Williams he missed the most important one: she was a poorly developed and downright unlikeable character. Her entire origin read like a checklist of cliches and her biggest problems was all of Tony's supporting cast as well as the in-universe media telling her how awesome she was and how she could not live up to their adulation. Yet Bendis had the audacity to say that the world had only shown "the back of its hand to her." Bullshit. While the deaths of her best friend and stepfather were tragic, she also had received a scholarship from MIT at fifteen so the world was not completely against her. Oh, and she stole the components to make her first armour whereas Tony make his with only scraps.
Then there was that page where she wanted her kindergarten/first grade teacher to tell her that she couldn't he like Tony Stark, when said teacher was nothing but encouraging. Riri Williams was nothing but a narcissist at her core.
