Are you sure it is just me, the BBC, the Guardian and every other agency including Labour List making it up?

Not making things up, I would say, but putting as negative a spin on everything as possible. For example, I am told there is an article in the Daily Mail on Sunday calling Corbyn a hypocrite for having T-shirts with a slogan on sale for his campaign 'where the workers are only paid 30p an hour' which he has previously criticized.

I admit that's all probably true. But I follow it by asking do you know anywhere in the world people who make T-shirts are paid the UK Living wage? I doubt they exist, because 'the capitalist system' would put them out of business pretty quickly through competition. So either you never wear or sell T-shirts at all (or indeed most other clothing), or you have little choice. And if that is the case, is criticising it hypocritical? I don't think so.
