The accusation is not that they alter pages at all -- they obviously need to in order to make some pages readable/functional, bypass paywalls, or hide account names used to do so. The Wayback Machine does something similar with YouTube to make old videos playable.

The allegation here is that they altered page content not just to remove their own alias, but to insert the name of the blogger they were targeting. That moves it from a defensible technical change for accessibility to being part of their bizarre revenge campaign against someone who crossed them.
