Show the problem exists which you try to solve. Point to instances who struggle financially, who consider running ads, something like that.
Not to mention that over the years there have been a lot of instances that have gotten into a variety of precarious situations that could have been avoided or alleviated if they had a lot more money.
- mastodon.technology shutdown because the admin ran out of bandwidth (family member was dying)
- mastodon.lol shutdown because the admin ran out of patience (some kind of nauseating fedi admin drama)
- switter shutdown because it didn’t have the legal means to comply with new online safety regulations that were being passed
- ownership of pawoo.net changed hands, twice! the first 2 owners figured it wasn’t sustainable financially to keep it online.
