High-powered computers are a niche issue, which means on a society level there's little benefit to restricting them.
Lightbulbs on the other hand affect all of society, so they've got a much larger impact to the overall CO2 budget.
Additionally, the average person uses a laptop or mobile devices, all of which use less power than even a single typical incandescent bulb (and people usually have many lightbulbs).
Replacing incandescent bulbs with LEDs saves a lot of CO2 at basically zero cost, while getting rid of computers saves less CO2 for a much larger economic impact.
And even the effect described by this article has to be looked at in context, considering most of the light people experience in a day — and have experienced for the since homo sapiens existed — is natural sunlight, even in northern Europe during the winter (that's why EU law mandates windows with sunlight in every office, apartment, bedroom, etc.)
