I think lying is too strong a word here. TfL have not said that all fares have risen in line with the national increase of 4.6%.
Whenever increases are applied to small fares there is always going to be quite a bit of variation given that the increased fare still has to be a multiple of 10p. There will be winners and losers, but overall the increase will be roughly the desired figure.
That said, the fares in zones 2-6 have seen an abnormally high increase. It should be noted that compared to NR fares, TfL fares are still competitive. I don’t know whether there is a direct connection, but bus and tram fares have been frozen, so across all of TfL the increase is probably just right.
The fares in zones 7-9 may have been an oversight (I genuinely dont know) and they may well go up more next year.
