Well, you should, because both C3 and Unity using a subscription model vs the one-time payments of many other options makes it the most direct comparison. Both concretely and psychologically a subscription model requires a much more serious commitment to the product compared to a one-time payment.
And beyond the payment model, I've long thought that Construct offers a serious alternative to Unity for serious development purposes if you're making 2D games, and in fact I'd say in many ways Construct has the edge over Unity in this space since it's built for 2D development from ground-up whereas Unity is a 3D engine first, which makes 2D development in it more cumbersome. This is why I was happy to see you mention in another comment that you intend to shift the marketing of C3 to a more "serious" direction, where C2 often gave the impression of a "toy". But that's just another reason why you should consider yourself as a serious alternative to Unity yourself.
I assume that the "direct competitors" you're talking of are along the lines of Clickteam Fusion and Game Maker. It's certainly true that these are both 2D-focused game IDEs, but both are sold as one-time payments, much like C2. As someone who moved from Multimedia Fusion 2 to Construct 1 back in the day, I personally think C2 has already been the king of this space for years, wiping the floor with the competition when it comes to both usability and performance as well as scaling to big projects. This is why I'm not at all fundamentally opposed to "going bigger" with a subscription model to compete against other subscription model game IDEs, because I believe C3 is very much capable of competing in this space, all the while having a lower barrier to entry. But again, to be competitive here, things should really change with the way the free edition is handled.
Ultimately right now Construct 3 falls into a very uncomfortable position where I would never want to downgrade to the likes of Clickteam Fusion (neither the current 2.5 nor the upcoming 3) or Game Maker Studio 2 (because they are both less powerful/performant as well as less usable on the whole and scale big way worse), but I honestly wouldn't want to use Unity either because while power-wise it's definitely capable I'd still be somewhat of a downgrade in terms of usability for 2D development (I have actually used Unity for a couple projects in the past, but I've stuck around with Construct 2 for this exact reason). As a professional programmer there isn't really any insurmountable obstacles to using any of these programs for me, so it's all about the convenience for me, and 2D development with Construct is where I believe the sweet spot lies in this regard. But as it is, C3 free edition is just too restricted power-wise and the subscription is too big of an investment. Because of this I also see myself having a hard time recommending C3 to other people in the future, where recommending C2 used to be a no-brainer.
