"pushing devs harder"

"ask devs to do mantainence in their personal time"

"they are free to do it if their manager allows them to"

"agile development team has different meaning in pretty much every single company that practices Agile"

These show biggest problem with people who think they understand Agile and modern development practices but they clearly don't. Some of these I find especially scary and I stand even further on my opinion that you shouldn't be writing articles like these until you got more knowledge on the subject you are trying to educate people on.
