It used to be dislikes and could be problematic in browsers like i.e but chrome, edge, FF and opera all manage it perfectly now
On my iphone websites are far more snappy without it along with avoiding the over use of advertising. Reading articles from the SMH on my phone doesn't pop up the pay to read feature or limitations of how many reads per month.
This site on my iphone 6 struggles at times and is far more snappy with it off, the advertising is too intrusive but totally respect the need to make money and fund the site so have no qualms about advertising in general.
Not really into too much web page interaction anyway and prefer the more simplified look with it disabled also.
