I saw this on the Ars website recently.
Of course, it’s not as simple as that, so it’s worth reading the article from whence it came.
Then there is Flash. Steve Jobs hated it but not because he hated Adobe. Flash was a power hungry plug-in which didn’t sit at all well with his plans for iPad (etc.). Of course, things have moved on a bit since then. Java and Flash have shown themselves to be, um, susceptible to hacking, malware, trojans, etc..
Java (JRE) has largely disappeared from our browsers and it is mainly enterprise applications which still rely on its continued availability (my daughter’s employer’s internet-accessed HR system for one).
Many websites still use Flash but they don’t need to.There is HTML5. Even YouTube doesn’t rely on it any more. So I think it is time for Flash to die. I’ll leave you to make up your own minds.
