If you’re gonna participate in a discussion within a specific community, I wouldn’t call it gate-keeping for others to expect of you at least a base level of topic-specific knowledge.

Apple silicon, within the tech community, and Apple specifically, was a major thing. It’s the reason Intel needed to up their game as it’s why Apple severed the relationship. It drastically increased both battery life and performance, while reducing heat. Even people who hated Apple took a moment to give credit for the industry advancement.

I expect Apple people to understand all that, as well as others in the computer hardware community. I think it’s fair to expect commenters in an “Apple Enthusiast” community to know what Apple Silicon is before they start bashing the company for total failure to innovate.
