The only one who seems at all hurt here is you.
The program is being extended because there aren't enough Australian applicants to fill the quota. If you had taken the time to read the 3 sentences in the OP link before becoming so outraged, you will have seen that Irish E-3 visas will only be granted to fill space left by unused Australians;
"For Irish E-3 initial applications, the Department of State may approve each fiscal year no more than 10,500 minus the number of Australian initial applications approved the previous fiscal year."
