First, there's a lot of talk (here and the earlier thread) that loosely equivocates fundraising with crowdfunding. They're not the same. To tell a project that it should simply accept donations rather than use a crowdfunding platform is a false equivocation. Crowdfunding's mixture of elements -- the presentation, the pitch of the vision, the element of a deadline, staggered donation levels and gifts -- is not replicated by publishing a "Donate!" banner.
Second, linking to a web site is not an automatic endorsement of its script licensing or the practices of its operator. Lacking semantic operators for hyperlinks, context is everything. Personally, I trust my readers to understand this.
