I understand companies need to make their profit, but seriously making debugger premium is just a very cheap move by LC, just start using gdbonline, something that can very easily be found for free, why make it premium? Other than making me copy paste the code in gdbonline and copy paste the input, it's not doing anything, and it's not like they came up with the idea of debuggers that they are monitizing it the way they are, other than a nuisance it won't be much.
Maybe it will allow them to get money off of people who don't know how to debug themselves at most, I hope it just pushes those people to learn instead of paying for using their debugger.
It's a good platform, and I'll continue using it for practice, now I can't complain in the sense that the community and the questions is good enough, but it was very disappointing to see it become premium all of a sudden.

They even took autocomplete out. Just hope they don't make all questions premium now.
