Unless the land owner doesn't agree to the purchase price
No. They can do it
against the will of the land owner.
But to reiterate, government absolutely
can take property (such as land)
against the owner's will.
Even if the land owner does
not agree to the price that's offered or determined as fair compensation.
Government can only do so on a legal basis of course (such as is provided for many construction projects). The taking authority is required to negotiate a fair price in good faith first. If there's no agreement, the land owner may of course challenge the taking it in court, which will determine if the taking is justified. And that may prolong and complicate the case, which is why in in practice the government agency may want to avoid it.
We have a project right now that the state government can't complete because the last remaining land owner won't agree to a price on easement and they can't eminent domain it without an agreement.
Eminent domain is the legal concept to be able to take it
regardless. Without an agreement.
Honestly, I think there's no point in rehashing that discussion. Anyone could consult the statutes of his directions, ask a lawyer or just read one of the more accessible explanations (such
as this one). It's very simple.
Yet you keep pointing to that one particular project of yours, for which government can't or has decided not to take such action. There may be good reasons or that (opposition in court or public, resulting in further delays or costs). Even if they can‘t your one particular case, that doesn‘t mean that government can
never do it against the will of the property owner. And it doesn’t mean that they always have to reach agreement.
Using a third party product that runs software isn't the same as iOS or Android.
What's iOS or Android? They're both open source operating systems that run a proprietary layer on top.
Same as for many utility or infrastructure providers.
And yet every single Spotify ad I hear is for signing up for Premium on spotify dot com.
Yes - and it may still not as comfortable as doing it in-app for many people.
Also, not every app developer has the advertising resources that Spotify has.
And they're not hurting because of it nor would they see any benefit from being able to purchase through the app.
I don't go to my bank's website, when I can make payment with an app more comfortably.
Also, an app developer may advertise "add-ons" and additional functionality in-app. It's additional "friction" from a user experience point of view, if I have to go to an external website (that Apple even prohibits them from pointing me to) and will lower the "conversion rate" of such ads into paying customers.
That said, as well-known as Spotify is and as relatively their range of subscriptions is, they probably may not even be the very best example of suffering from the Apple tax.
