There's a difference between "extended features for commercial versions" and "adware". Usually the open source version includes core features that solve a basic set of problems, and the commercial versions add additional features to solve other and/or larger problems. At no point is there an explicit crippling of the open source. What's particularly frustrating is the burying of the lede here. The summary of the page intentionally omits the fact that you can build from source and use it in commercial contexts. And the section discussing the Apache license is factually incorrect: "Remember that building Caddy from source is still subject to the Apache 2.0 license which requires attribution and stating changes." -- that is only true if you are selling on-prem software that ships with the program. If you are using it in the normal course of your SaaS, no attribution is required.
