What's a list of Stack Exchange sites that are dedicated to a product or company? For example, Ask Different is dedicated to Apple. Ask Ubuntu is dedicated to...well... Ubuntu. Are there any rules relating to the creation of Stack Exchange sites dedicated to products or companies?
The instructions at How can I propose a new site? place no restrictions on proposing the creation of SE sites dedicated to products or companies.
Those instructions should be read in conjunction with various ideas for What makes a winning site proposal? to decide whether a particular product or company may be suitable to propose an SE site dedicated to it.
I'd say a lot, depending on the criterion of "dedicate to".
Here's a list of sites that "dedicate to" a specific product or products of a specific company.
