There's a lot of customer culture attitude in Mastodon-the-community, where people treat Gargron and other devs, the instance admins, moderators, etc. like service workers. It's a spoiled, entitled attitude, where "the customer is always right" and it's okay to be abusive or demeaning to people providing a service when they don't give you what you want.
The fediverse isn't a corporate model. When you're rude or demeaning to someone here, you're being abusive to volunteers building a playground
