I work for a sales team that uses one of these tools. I think one part of the picture that you've left out is that (at least in our case, and I suspect in many other companies) it's actually the junior sales reps (SDR/BDR/etc) themselves who are using the tool to scale their own prospecting communication. So I don't think it's necessarily quite as malicious as OP believes; these are emails that the rep would be sending personally, but the tool allows them to automate parts of the process and scale up their volume by an order of magnitude.

Much of a BDR's job is to find an email template that works for a certain type of prospect, and then to find as many of that type of prospect as possible and send them that email. You can expand this to a 'cadence' of emails. But whether or not they are automating their work with this kind of tool, the prospect's experience wouldn't change much.

Edit: I should also add that (again – in our case) we push our BDRs to send one-off, personalized emails and get on the phone as much as possible. They're ultimately judged by the amount of business they generate, not how many prospects they blast emails to.
