Same here, I tried to show willing and turned off my AdGuard & Ghostery. I know the site needs the revenue but without them the tab icon spends an eternity spinning before the page loads completely and the PC becomes laggy and slow to respond. I'm on a passable broadband link but the unhindered load of the pages grinds things to a snails pace.
The way I see it is that the people who develop these sites are using High Spec equipment which is well able to cope with the demands that they are imposing. They don't consider those of us who can't keep upgrading to the latest equipment. There used to be an understanding where by things were aimed at the lowest common denominator but I suppose that isn't financially acceptable these days.
