Mr. Bybee,
What Mr. Roos has expressed is precisely my feeling as well.
I do not think that Mr. Glesser is wrong for speaking out on the Forums here or anywhere else -- it's just that as your own closing stated, there's been way too much negativity going around on this particular issue as-is, and further lay debate here is not going to do anything but agitate what residual angers and ill-will is left. It's now, IMHO, way past time for this issue to be settled in a big-boy way, to let it play out in the courts if there are indeed any true concerns left.
Your sentiment, Mr. Bybee, is exactly mine as well.

And while informing another company/maker that there is an issue is certainly valid, as per your own thoughts, mine, and that of Mr. Roos, at this late time, it is no longer helping, and is serving to perpetuate ill-will.
As for your question of:
How can a knife company be wrong for not knowing about a knife pictures that exists on the internet, but be wrong for speaking out on the internet?
This question answers itself, within the wording of your very sentence above.
If the Internet is going to be one's stomping grounds, one should have sufficient resources devoted to it to be certain that they're up-to-date and on-top of the breaking headlines.
Spyderco is a well-respected company, one with engineering innovations and market foresight. Among what impresses me about Spyderco is that they are truly dedicated to this market, and their expertice in this field is second-to-none.
Their speaking out on the 'Net about this knife, as well as their specific aims within the market overall to police inappropriate and unlicensed usage of the SpyderHole, to me, shows more than sufficient drive but improper execution on the part of those whom Mr. Glesser and Spyderco employs as their legal and research team. Obviously, they know that the Internet exists and are using it towards both their as well as their fans' profit and benefit, however, their ignorance of Mr. Blackwood's designs and projects executed in living steel - seeing specifically that his custom cutlery and designs is nearly born of the Internet but its reputation and worth has already spread much, much further than that (no true knife enthusiast, however new or uneducated, who happens to have come on to the scene within the past year or so can plea ignorance on the Blackwood name from the amount of show-talk as well as print and other common-media coverage generated about his works; I myself, as you may have noticed from the USN and here, am only a beginning enthusiast) - is at the same time both inexcusable and puzzling.
It's as if those individuals involved in such research only decided to take their dedication so far. Had this been true of any other professional - for example, a medical doctor - it could easily have been called malpractice, and shows negligence at best.
As a Spyderco fan (and I truly am, I own and prize several Spyderco collaborations, and have recommended Spydercos to friends ranging from office-workers to LEOs), I find this oversight simply appalling -- all the more so in that Mr. Glesser specifically cited that there is apparently an entire section of the company whose chief working objective is to stay abreast of such issues.
