So you think it's unfounded to assume that them merging with a malware company means they will start installing malware somehow? I think there would be _no other reason_ to merge with a company that makes malware? Maybe it won't target devs, but the concern is no unfounded.
Absolutely, there's no shortage of reasons to hate on Unity or this merging, they have done so many things wrong it is infuriating but thinking that they would include malware as describe above forcibly, making any games made in Unity unpublishable on virtually all stores makes no sense.
Unity game dev will, willingly, include ads into their games, no need to sneakily force malware on users computer for that.
I get the fear, "unfounded" was perhaps the wrong word, most articles want to push the narrative this way, but despite their previous sketchy background, IronSource is one the leading mobile gaming ads company, they don't only make malware and clearly this merging is about "ads" and not installing malware.
No. I really don't see the concern. Unity's business model does not involve targeting users with ads by installing malware on their system. However, many games studios do choose to integrate ads into their game loop and as a game platform I can see exactly why Unit wants this type of talent in-house so they can make their platform more attractive for game devs that might be looking for this type of feature in a platform.
Ads are malware. The reason ad networks use the same techniques as other forms of malware is that they're both trying to make the computer behave in ways that its owner doesn't want.
