The start of the article says:

The lazy answer is always "weaker hardware at home." And sure, that's part of the story, but it's a small, almost surface-level part.

yet nearly the entire article is about consoles having weaker hardware, and the fact that console controllers are not specific to each game (which I'm also including in the "weaker hardware" bucket).

The only point that's not about weaker hardware is that arcade games generally have a higher difficulty since they want you to keep dying and inserting more coins, whereas console games are more balanced.
