Telling the truth doesn't mean you have to insult your customers. You can do it politely and correctly as long as you use reasonable terms.
I wouldn't feel insulted if they just wrote "Sorry for the annoyance, but we are going to split the bundled games because it's necessary for us in the process of porting libraries on GOG Galaxy
". I could have disagreed, but i wouldn't have feel insulted. I feel insulted NOW, because they are insulting my intelligence with blatant lies. Not caring for your actual customer base because the growth in new customers and maybe a couple caresses in the form of gifts and nice promos will counterbalance their annoyance is a risky move. Larger and more powerful companies have suffered greatly for similar thoughts in the past.
Personally, i don't even dislike the idea of the client, as long as it adds good features. But when it comes at the cost of usability, it's a whole different beast.
Thing is that they can't come out and say that now, because one of the points they made and emphasised when they first announced the client is that no one's experience would change because of it. Saying now that the unbundling is for the client makes their earlier, repeated statements a lie, so they try to spin this as something they're doing to satisfy the demand from the user base (see, we still care about you!) and pretend that it comes with the added bonus of making things work (better) with the client.
Why can't I opt out of this madness? I've already lost track of my games thanks to your bad search engine and the missing mails after redeeming a gift.
Because that would give you a choice?
Since when has Steam become the golden standard? Perhaps GOG should aim to be different from Steam, rather than attempt to mimic it.
Ever since it saved PC gaming?
