There are always exceptions, we are talking about the general case. Anecdotally, in my professional experience every commercial developer I've worked with or am aware of will always avoid any copyleft-licensed material and many license agreements for third-party platforms prphibit their use. Yes, some platform holders will use it themselves, but that is not their preference. Ultimately, image encoding and decoding is a crowded market with many alternatives and I strongly believe that a copyleft-licensed component will always be passed over in favor of alternatives unless it is overwheingly compelling and a viable option. Some companies explicitly prphibit the use of any copyleft licensed software in their development. Certain conditions of the GPL and LGPL are impossible to fulfill on some platforms. With that in mind, I feel like my assertions remain reasonable.
