Not only are those terms overreaching, they are copied from elsewhere. Search with Google for "a non-exclusive, perpetual, irrevocable, royalty-free, fully paid-up, worldwide license (including the right to sublicense through multiple tiers)" and you get quite a few hits. Mostly from small businesses.

Primrose Schools, Rita's Ice, Small's Sliders, Transom Capital, and quite a few other small companies use exactly those words. The first three are franchisors, and the last one is a private equity company. None are in the social media business, for which that clause is clearly intended.

Do all those companies use the same low-budget legal drafting service?
