Then you probably should have double checked before signing up to an e-mail server dedicated to "Explore + Share beautiful e-mails without the letter P in them". Pixelfed is extremely open about being a picture platform.

Then this would be pretty shitty.

However, pixelfed is very straightforward about the fact that the focus is on image posts and even if they would not advertise that fact you should realize in less than five minutes of using it that all the posts you see are image posts.

Additionally there are enough apps out there that show all content (I use the default mastodon app to see image posts as well as text posts, etc.). If this is what you want just choose that app.

And if somebody makes an app that only shows text posts then this would be great for people who only want to see text posts. I really don't get the authors problem.
