One major danger that GPLv3 will block is tivoization. Tivoization means certain &ldquo;appliances&rdquo; (which have computers inside) contain GPL-covered software that you can't effectively change, because the appliance shuts down if it detects modified software. The usual motive for tivoization is that the software has features the manufacturer knows people will want to change, and aims to stop people from changing them. The manufacturers of these computers take advantage of the freedom that free software provides, but they don't let you do likewise.
