The meme features a character with a sly expression. The text says, "It's NOT vendor lock-in" about Secure Boot and then suggests saying, "It's for security reasons!" This implies that Secure Boot, a technology that restricts what operating systems can run on a device, is being used to lock users into a specific vendor despite claims that it's for security. The character's sly look hints that certain evil corporations are doing this deceptively and on purpose.
