I'm an Entangled author and have had an excellent experience with both ebook and print.
I'm also published with a big 5 publisher.
While my experiences with both publishers have had their down sides, I can tell you that the editorial process is much the same. While no author wants to be told his/her book needs major changes in order to fit the line or a publisher's perceived industry standards, it's part of the business. I made huge changes for editors at my big 5 publisher and Entangled. The requests were delivered in very much the same way and on similar schedules.
Turnover in this business is ridiculous in all houses. Huge publishers and small alike have personnel changes. Entangled has grown very fast and perhaps that accounts for some of the turnover. I can't speak to that.
What I can speak to is only my own experience. I have friends with big 5 publishers who are miserable. I have friends at small presses who are miserable--often for the same reasons. Authors often feel low on the totem pole (for good reason), and not in control of their work or success. This is universal. I feel no more helpless with Entangled than I do with my big 5 publisher.
Despite the feeling of helplessness, which I firmly believe is the nature of the business, I am thrilled with the editorial talent in both houses. Entangled put me through four rounds of edits, and then, I got kicked back out at Q&A and went through several more rounds, then copyedits and proofing.
Exactly the same routine I went through with my big 5 publisher including multiple editors.
I'm glad they kept making me change things. The book is so much better. It is category romance, and just like with category lines at Harlequin, it is a trope-driven genre.
I write for a living, and just like any other job I've had, I try to keep myself at arm's length from the project, while keeping it my own.
If I ever write a book I'm not willing to change dramatically, I will self-publish it. In today's market (unlike when I began), an author can put out the book of his or her heart exactly as it is written and have success. It is so great to be working in this business at a time when we can control every aspect of the project and make money doing it. That said, if I choose to publish with traditional publishers instead, I'm going to have to be willing to play by their rules in order to benefit from their platforms and reputations.
Now, I'm not saying that people don't have awful experiences. Clearly, Le Mole did. It happens at every publisher. My own experiences at both Entangled and Penguin have been excellent.
I am in no way trying to demean or refute Le Mole's personal experience. And I agree that you should go in with you're eyes open. I think this is true of any publisher, job, relationship, whatnot. I just want to convey that there are two sides of this coin and everyone has a different experience. Mine just happens to be positive.
