"If it bleeds, it leads." News media will rarely say something positive about any tech company, probably even worse so than the general bias towards negativity
If you think that's true, you should check out all the glowing write-ups of Theranos, Amazon (specifically Bezos), and Microsoft (specifically Nadella). The coverage isn't/wasn't universally good, but I think we do get a pretty good picture of most tech companies from mainstream media.
Looking at the last week, I count at least five positive articles about tech companies, including Apple's new iPad, Waymo's expansion, an AI VFX startup, Dropbox's IPO, and Safari's picture-in-picture mode.
