ThomasV is only develop Electrum for bitcoin, but there are some others wallet based on Electrum which have existed for years and have been shown as trusted. I have personally used ElectronCash for BCH, ElectrumLTC for Litecoin and ElectronDash for DASH. How much can I see on their official sites, developers of this wallets are active and new releases follow current events.
My opinion is that your advice has no legitimate basis, maybe you not trust in something for your own personal reasons, but that is not the reason why others should avoid something.
Not the wallets have to be trusted, but the developers.
As for my self, i do not trust a random developer (Calin Culianu ??) who decided to voluntarily develop a free wallet for a currency which is doomed to fail and which was obviously just an attempt of a few people to get rich quick.
