Why do they have to use actual companies’ exact names and logos to make their parody, which someone could confuse for a real product? Can’t they use slight variations (e.g., McDowels to parody McDonalds)? Wouldn’t everyone still know who they were referring to?

Edit: Yes, this is satire, not parody, and satire needs to clearly identify its target to work properly. Here, however, the target of the satire appears to be carbon offset sellers, as a farcical “life offset” seller. The companies in question are linked as mere “supporters” of the satirical service; they don’t appear to be the direct target of the satire.
