This is a valid use case for a corporate instance of a server. If a big corporation did invite a mass of users to the platform, it would still be a win for the platform in my book. The platform itself doesn't specify any restrictions on big servers just because the owners of these big servers are bringing in new users that they have influence over. Deeming a valid utilization of a platform as a 'real danger for the Mastodon/greater Fediverse community' misses the point.
