The community is full of plugins that force us to register on some resource in order to work with them, although they are marked as free. Often even trial-mode is missing. I donโt want to waste time on something that might not be useful to me. I have no doubt that many of us will be concerned about whether these email addresses will be used for spam or sent to third parties as well.
So in general, Figma people, come up with a way to filter such plugins (or at least add a mandatory flag on the page) โ this will make life easier for many designers.
