Is my internet usage to high?

I'm a very high achieving 15 year old guy. I have only really gotten A's even when I don't try and rarely a single B in the year. I wake up at around 6:50 for school and am back at home around about 5:00pm. I spend an hour and fifteen minutes chilling with my friends on the bus, on my way home.

I enjoy video editing, computer programming, making music on my launchpad and playing computer games as my "Computer Hobbys" I don't really play violent computer games, the worst thing I do is Minecraft PvP, which is hardly violent.

Outside of my computer, I play guitar(Grade 7), Drums(Grade 3), I play rugby in the winter and Cricket in the summer (A little obsessively I will admit ) as well as listening to music and other "Teen" things.

Midweek I can use the computer from around an hour to maybe four hours once a midweek. At the weekends I probably use the computer for maybe five hours in total. My problem is that my parents think I spend this time exclusively playing minecraft and therefore think I'm addicted and are looking to "Press Charges"

I probably during the week at the most spend 2 hours playing MC and at the weekend 4 hours. The rest of that time I spend video editing, either for myself or friends or coding in python or HTML.

They are looking to limit my time to at the most 2 hours for everything both midweek and at the weekends. They have really been "Studying" this, both reading very biased articles on the internet and informative magazines ( that are hardly as bad ) My problem is that if this change were to take place my new £740 computer would be a waste and many of my creative outlets (Coding, video editing, etc.) would have to stop.

I can find no way to negotiate with them. I need something that would, rather simply, blow them away and release their "Vice-Like Grip"

Thank you!

Added (1). Yes, I did use the wrong too. Sorry.

Show them some of the videos you have been editing and the programs you write. Then maybe they will realize that you don't just play Minecraft. Maybe you could make a compromise, like promise to play less minecraft if you can have more time.

Haha no its perfectly fine. I'm in school right now and our school give us free laptops, so I basically spend my whole day on my computer. But, are you sure you're being totally honest about everything you just said? If you arent fooling yourself, you are just fine
