If your company, media org, school, nonprofit, or fraternal organization wants to participate in the fediverse, there are two reasonable ways to do it:

1. Pay employees to run an instance.
2. Pay a hosting company such as https://fedi.monster to run an instance for you.

Making an account for an organization that has cashflow, on an instance that's run by volunteers and supported by individual contributions, is incredibly bad form.

(Maybe some instances will decide to accept organizational accounts, possibly in return for a support fee; that's on them, and I'd be happy to hear about such decisions. But it's certainly not a default expectation!)
