Do you understand that providing some examples of the opposite doesn't show "all"? Your goal is supposed to be proving the examples I gave wrong, not adding new examples, because I'm not the one that said "all". So what we've learned today is that different companies are doing different things and that blanket uninformed statements don't contribute to anything. Cool. You good?
Oh and if you want to use the ampersand for etc you don't need the t. Ampersand is "e" and "t" together! I hope I've helped whatever goal you had in choosing to write "&tc".
