That's a lie mixed with some truth. They have a download limit yes, but one that resets every 24 hours. You can download free 5 books even without an account, and with an account 10 and even more if you used the telegram bot. Like other user mentioned, that policy probaly was to discourage datahoarders and scrapers. And if you donated to the project you recieved the benefit of being able to download more books per day.
