I disagree. Twitter doesn't own that content. Someone posting the Twitter JS on their website to allow Twitter to format the tweet to Twitter's brand standards and allow a link to drive traffic back to Twitter is a favour that they're doing Twitter. They should respect that favour by not changing the contract unilaterally.
Yea, I don't think people are embedding tweets on their sites to do Twitter a favour ... it's because they want to reference something and part of the TOS says to use it.
You rightly point out the ridiculous claim, noting people don't use embeds as a favour to twitter - and then make the ten times more ridiculous claim that people are using embeds because of the TOS.
At least try and hide the fact you're being bad faith if you're going to engage like this.
