If an alien species is technologically advanced enough that they can cross the universe, I find it hard to believe they simply wouldn't understand concepts like stealth, strategy, etc. However, I'm skeptical of there being any intelligent life out there that we could feasibly communicate with on any useful timescale anyways, so I don't necessarily disagree with you. I just don't think this argument is inherently sufficient.

In terms of other life observing us broadcasting radio waves is rather small and limited. However consider the galaxy is much older than Earth. That conditions on Earth to support life is around the span of ~2 billion years. The galaxy is under 100k light-years across. That's a fair bit of time for the possibility of some other life within our galaxy to detect atmospheric signs of life supporting chemicals on our planet and to send a probe to investigate. I don't think it means aliens have visited or sent a probe but I think it is possible.

  Intent is a big deal. If we assume a hypothetical visiting extraterrestrial species wasn't wishing to do us harm and didn't wish to cause alarm and disrupt us, we can assume they would want to minimize contact if they didn't feel it was appropriate. This is also assuming they would even have the same values as us. We send probes and signals out, clearly we want to make contact, so they may see no problem with not using stealth, especially if it saves resources for them by being a little more obvious but still avoiding contact.
