It depends how you forward images. I assume they are referring to how many/most services (like whatsapp/discord/telegram etc) don’t just send the original file, but do some compression to save data. Do this a bunch of times and you end up with a photo that starts to show noticeable artifacts/pixellation.
That’s my take at least
