I am OK with the ads, as long as they don't interfere with usability. If you are using an ad-blocking rom, you should be going through your app list and making donations to the developers of the apps you use. I also have spent about $20 on apps with no regrets.
Also, places like Android Central are largely ad-supported (AFAIK). I used to use ad block plus, but no more. I still use no script, but I white-list places I frequent. I also donate to things I often use.
Full disclosure: I am a developer, but not a mobile developer. I just have sympathy for them.
Things take time and money to develop. Wikipedia is begging for money. They don't serve ads. If you have not already, consider donating to them, if you use it. X-Marks may have a new lease on life, but it nearly shut down because it didn't have the funds to continue operating.
