Do you not understand how ads work? It’s about making sure that IBM is the first company that comes to mind when you think about potential suppliers for an upcoming project.
It’s no different than ads for Coca Cola. You know what Coke tastes like. An ad isn’t going to materially influence whether you like it or not. However, it attempts to keep the name present in your mind so the first thing that pops into your head on a hot day is a nice cold Coke.
The fact of the matter is that people will happily pay for content if it is made available in a convenient and affordable way. Hell, many people will voluntarily pay artists for content that is available completely for free. That’s how patreon works, and there are self published authors approaching $1M/year in income due to readers choosing to support the author for their hard work.
People have no issue paying content creators.
Piracy rose to prominence in the 2000s because a few executives were funneling massive amounts of money into their pockets by the sale of CDs and cable services that were simultaneously expensive and inconvenient. The studios attacked pirates directly to little effect because you simply can’t stop the free dissemination of information among the public.
Piracy almost completely died when streaming made the alternatives affordable, user friendly and convenient. In a world where the proliferation of streaming services is making content just as expensive and inconvenient as in the old days of cable, it’s only natural that piracy will once again rise to prominence.
If they want to get paid, they simply need to stop fucking with the customer and offer a service people want to pay for.
