> The phrase after the "but" in the second sentence isn't the "summary definition". It's the part of the definition that best supports your argument. Cutting the Wikipedia definition down to that part is deceptive.

Everything after the "but" is what Google means when they use the term sideload and is the only important part of the definition for f-droid's purposes. The other definition is completely irrelevant and, I would argue, hardly ever used anymore.
