Indeed. Just as importantly, developing a single image with license-enabled features saves both vendors and customers a lot of time on QA, acceptance testing, etc. Since you're always running the same image, you only need to test it once, with all features enabled, to be sure that everything works; if there are different images for different feature sets, you have to run a full test suite on each image. That's a lot of extra work for no real benefit. Having to switch from one image to another to enable a particular feature also entails additional risk, downtime, etc. that simply loading a license key does not. > Even CPU manufacturers are noted for artificially restricting features > in software (such as VT or hyper-threading, even artificially > disabling cores).

Indeed. Vendors face a lot of price pressure, so being able to disable non-mandatory features to meet low-end customers' price demands is a major competitive advantage. However, they still need revenue to support the development that the handful of high-end customers demand for "new" or "optional" features, and charging for licenses to enable those features seems to be the best way that anyone has figured out to do that. Heck, I work with one vendor that requires separate licenses for virtually every checkbox in their GUI; turning up one customer port may involve purchasing dozens of new licenses. The customers of their product don't like it, sure, but suggest that they pay the full cost of enabling all options on all ports and they flip out. Licensed features enable customers to purchase only what they need, not what some marketing puke decides they need (or some one-size-must-fit-all pricing scheme, which rarely works well).
