So, no, your request is not reasonable.
I'm confused what you mean by saying that the employees of a business don't need to read these legal texts but that the "business" should read them. The "business" is not a physical life form that has the ability to read, only the employees of a business have that ability, since they are humans (unlike the business entity itself, which is not human). Perhaps your idea was that businesses should hire a team of lawyers whose only job should be to read through the various ToS and EULA legal texts that their other employees merely click-through?
If you as a buisness sign up to amazon web services to host your entire backbone on, you better read the contract. If you don't, you are irresponsible.
Someone, somewhere at the buisness should take the time to read a simple little document before using it as the backbone of everything they do at a company, yes. It does not have to be a lawyer...
I'm extremely sympathetic to the idea that there are too many eulas for free products, things like games or whatever where it really doesn't matter for 99.9% of users. But for the 0.1% that make their livelihood from the program, they should take the 25 minutes to read through it at least once.
I'm not saying this because im a big bad lawyer that hates you (I am not a lawyer at all), im saying it because it's a tiny thing you can do to save a whole lot of heartbreak.
You just gotta decide when its important to read contracts and when you don't care. I don't care about the contract when I get new lenses for my glasses, or when I pay for netflix. But if im moving into a new house? I read the bloody contract.
Yes, but there are two sides to "resonableness": The "what" side and the "who" side. "What" is the thing that should be resonable. But the overall resonableness just as much depends on the question: "for whom is this reasonable?". While a consumer cannot possibly be expected to really read all the ToS everywhere, a business maybe can be expected to do so. Especially for things that are very critical and integral to the business, like the license of that one framework you are building all your software upon. So I do think requiring a business to read and understand the Unity ToS is totally resonable.
The law often makes use of the reasonableness standard. I'm hard pressed to believe that carefully reading the hundreds of TOS and EULA's hoisted upon us is reasonable.
If you're reading my comment you must have read the TOS/EULA for ycombinator, firefox (or chrome), your wireless or ISP, the keyboard app on your phone, odds are you have an email, perhaps a google account, remember the OS licence. Ever listened to a music streaming service, watched youtube? Messaged using an app? Banked online? Have some managed passwords? Like games, how many? For the common people, what about social media?
That's about a dozen "contracts" and that's lowballing it, multiplied by each update to the "agreement" (pray they don't alterate further) multiplied by the requirement to also read and acknowledge the privcy policy. All this for services that have become when not essential ubiquitous and constantly shift under you. You'd need 8 figures to run that by a lawyer, or a part time job to carefully consider. That's not a reasonable arrangement.
