Should the right to make a profit, trump the right to not be bothered?

In the last years I've seen new strategies to convert potential customers into actual ones.

I am from austria (europe) and I have a particular view about not being pestered while I'm in my decision-making process. If I want help, I ask for it.

But I registered while working with usa branches, that some americans have a different perception of it. They actually expect to be pampered to some degree.

The question, because since I'm just one person.

Do you actually like getting this super attentive approach? 'Hey, can we help?' When you just want to skim through a feature and price-list? on a homepage?

Or the classic shaming strategies 'If you are not doing this, blablabla' ? 'people will miss you blablabla' (facebook deactivation of your account)

In general I don't mind having a chat-bubble for support, but I want to activate it.

Same goes for the 'we miss you approach' instead of a 'if you leave you are a bad person - because approach'.

I know they are less effective because they are less imposing.

They seam to have a measurable impact otherwise companies would probably not use them increasingly.

So the question remains.

Is it okay for a company to pester us to pitch their sales? As a business person I see the appeal, but as a citizen I get annoyed by having 10 adds and 1 letter in my mailbox.

What do you think?
