It's kind of annoying, but less so if there's at least some logic to it. I can get pretty much everything I need as a shit-tier home handyman from Ryobi's 18V range, but if I were a more committed gardener or DIY I could imagine I'd want their 36V range as well. And then be irritated that the higher-power range only covers some tools.
All that said it does seem like, I dunno, a relatively pointless complaint. Are there people who are that keen to mix and match their Bosch and Ryobi? It's all much of a muchness.
