We're left to guess at what the point is but I doubt that Barclay's use of javascript, cookies and analytics platforms are what Razer is pointing out. I presume that Razer is miffed at the obvious indoctrination play that comes off as a bit creepy. Perhaps Razer would like to see a Cpunks themed playground where opsec is taught to toddlers?

Barclay's bank, you know they're cool because they use the wrong symbols for punctuation and substitute letters for look-alike glyphs.
