Edit (rather than reply and make the comment chain long): It's fine that you read it that way. I figure that if the article were about a launch vehicle then it would have been the rocket's name in the title, and if the article were about the satellite then it would have the satellite's name (BOTSAT-1). If Botswana had developed both an orbital launch vehicle and their first satellite then I'd bet the headline would have been sensational.
Sorry to go meta here, but this is just rude, both to OP and to other readers.
For OP, you're effectively pre-empting what they say with your own counterargument, and even more so you're removing the ability for them to counter your counter. You're essentially using the edit feature to end the conversation and ensure you have the final word.
For other readers, you're introducing confusing non-linear flow.
Just reply. It's not hard, and as you can see below you didn't actually prevent a subthread from forming.
I've noticed this more and more, especially on more controversial topics (which this is certainly not).
Adam makes a statement, Betty responds. Adam responds, and Betty edits her initial response and conversation ends, likely because Adam didn't see the edit.
Adam makes a statement, but the responses show the statement was unclear and/or leads into tangential arguments. An edit can clarify the initial statement for future readers without getting the original poster stuck in the back-and-forth necessary to escape whatever quagmire the unedited version created.
