If protectionism for football players is what gets Mr. Dickovick started, for me it has certainly been patent, especially in regards to software - although as Stiglitz has shown, the same issues are relevant for almost any patent, not the least in medicine and other research.
I know, throwing stones at Microsoft for their less-than legal and more-than disgusting market policies has already gotten old, but they certainly deserve every single one. No everyone may realize that just having a shiny brand on it (Microsoft, Adobe etc.) does not automatically make the product better. As a proud user of open-source technologies - from text editors and Internet browsers to video, sound, graphics processing and on to the more obscure areas - I can assure you that the free alternatives are as good as, if not superior to their pricey counterparts. The biggest irony is that while "open source" can be claimed to stop innovation (in the same way as the argument against free-flow of knowledge in scientific research that Stiglitz mentions), it does just the opposite, making things easier to use, for free. To give you a few striking examples - Open Office can work with about twice as many formats as Microsoft Office, including easy conversion from .doc to .pdf. On the other hand the M. Office, if it did anything "innovative" at all, is it sacrificed pragmatism for form, and used an ingenious mechanism to ensure that the customers will HAVE to buy their new, and in many people's opinion inferior product (some pretty monopolistic behaviour there, too). Another fun one is that Microsoft got the idea for tabbed browsing for its new IE7 and 8 from Netscape or Opera, where it has existed for years - and had they patented it, they could've made a hefty sum. So much for "protected innovation".
I am also positive that the people who grew up in the 80s (and in some countries even 90s) would be sad if Sony Corp v. Universal City Studios were decided the other way. And I am sure, had the Supreme Court ruled the VHS recorder as infringing on copyright, the DVD players and recorders, iPods and many other 'no-brainer' everyday entertainment technologies would have been a lot more difficult to get hands on, if they ever were invented in the first place.
Of course, a VHS player is not as critical to the word development as malaria drugs, but perhaps such examples are necessary to get the people in the developed countries understand the problem. If you don't allow free flow of water, it stagnates; knowledge and information are much the same. And now, as I proudly close my Opera browser, I will let you think whether (and how) we need to pick up our verbal flamethrowers to take those nasty 'thickets' down.
P.S. When I saw that phrase in Stiglitz, I literally went "Aha!" in my head. Way to feed my blog more opportunities for obscure metaphors.
