Many companies in the industry mislead users about encryption and just try to use it as a buzzword to attract customers. Take Apple, as example. Apple cloud backups are not E2E encrypted by default (like Telegram chats), and even if you opt into E2E encryption, contact list and calendar won't be E2E encrypted anyway [1].

Yet, Apple tries to create an image that iPhone is a "secure" device, but if you use iCloud, they can give your contact list to government any time they want.

Apple by default doesn't use E2E for cloud backups, and Telegram doesn't use E2E for chats by default. So Telegram has comparable level of security to that of the leaders of the industry.
