If clients are open source, I will surely link to the code.
Some clients are still closed source, but will be open in the future. In that case, I will also mention that.
I will not give recommendations, as each reader will have to decide for themselves.
I myself am personally not bothered by some closed source clients, especially if I trust the developer, but some people find it very important.
That's totally OK.
The idea is to get all relevant info out there, so people know there are alternatives to the NRS client.
