it can:be, but on Discord for instance I find myself manually removing the embed of shared links 90% of the time because it takes up half the screen and the image is just a massive logo.
On mastodon I don’t even have the option to opt out of embedding afaik. All I ever really want for sure is the descriptive text, I.e. the first paragraph (or bespoke description) of my article.
At the very least I’d like to ensure that my image thumbnail is always *tiny*.
